To' all whom it may concern,.-

' Be it known that I, JAMES POTTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement Iin Universal Lubricators; and I do hereby declare the following to be full, clear, and exact description of the invention, reference Ybeing had to the accompanying drawings, and figures of reference marked thereon, which form a part of this specification.

parts of my device, I have designated the sides In order to fully understand the different ofthe receiver, the front and back sides, andl right and left ends.

lIhe obj ect of my present invention is animprovement on my patent of June12, 1883, No. 279,181, in the manner of construction and in the feeding of the wick outward as fast as used up, and in the regulating of the iiow of the lubricating compound, so that I can use other classes of compounds or liquids than those mentioned at that date, and so devote my device to other uses. The reservoir A is made hollow and fashioned flat one way and cylindrical the other, the fiat parts extending down and forming the end walls of the receiver B, Fig. 2. From the cylindrical sides I also extend downward the piece of material that forms that part from the point A', to make the front and back walls of thereceiver. I unite the said parts by soldering the surface of the cylindrical parts to an L-Ilange, B, formed on the outer edges of the flat parts, by which means I avoid bringing the raw edges of the material together and make a closer joint.

On one side of the reservoir A, Fig. 3, is an opening, b, through which the lubricant is inserted and afterward covered by the screwcap C, Fig. 7. z

Upon the right and left end walls of the receiver B, soldered thereto, at a and a', are the blanks B2, on the outside edges of which I turn an L-f:lange, B3, which stand inward when mitered to the said walls, Fig. 5. Y

and also feed the same out as fast as worn off.

The movement -of the slide is indicated by the dotted lines in Figs. 12 and 13, the curved shoulders c in the flange B3 forming the guideway for the downward and forward movement, and-the shoulders d the stop, to prevent the slide from moving back while holding the In Fig. 13 the slide is represented in the latter position. hold up the slide in its vertical adjustment and withdrawal from the wick to obtain a new.

hold, the upper ends of which are soldered at A to the front wall of the receiver, and have a bearing against the slide at their lowerends. Upon the outside surfacev of the slide is fastened the thumb-piece D2, the pressing down of which, with the assistance of the springs E, causes the movements previously referred to. The teeth D', in operatin g the wick, enter slots The springs E assist and @,Fig. 3, cut into the receiver, whichV are a 4 little wider than the thickness of the teeth, and long enough to allow free action thereof.

Securely fastened upon the opposite side or back wall of the receiver B are the springs F, that form part of the mechanism for controlling the ilow of the lubricant. Stretching across and above these springs is the rod G, passing from one end of the blanks B2 to the other, and projecting beyond the same on either end.' Upon one end is the thumb-piece f, by which the rod is revolved. Placed at a certain distance from each end ofthe receiver upon said rod are the cams II, which rest against the springs F. The rod G is held in the center by the clamps I, whose ilanges I' rest upon the back wall of the receiver. The whole operate to retain the rod and the cams in the desired positions in regulating the iiowof the lubricant. The screw J is intended to tighten the clamps I on the rod G- when in the working of said rod the friction has worn the clamping part away..

The device for holding the wick is'eomposed of one piece of tin or other material bent at the upper end so as to form two parallel pieces or clamps, L and L', which embrace the wick on either side and introduce it into the receiver.

In the clamp L, Fig. 15, at the lower end, are out slots 7, corresponding in size, width, and length with the slot-s c in the receiver, through which the teeth D' reach in working out and holding the wick.

To the clamp L', Fig. 13, on the inner side, is fastened the interior lip or jaw, L2, so arranged that it is the same width as the said clamp and about a third as long. The lip L2 is soldered at its upper end to the clamp L' in such a way as leaves the lower end free to work back and forth, as regulated by the springs F.

Into the clamp L', at the lower end, are cut holes 71, which correspond with the slots i, Fig. 4, and form openings for action of the springs F.

The operation of the entire mechanism for controlling the ilow of the lubricant is as follows: The turning of the rod G by t-he thumb-piece f revolves the cams H, which force the springs F against thc lip L2 through the openings 71. and i, causing the said lip to squeeze the wick at its lower end, and so control the iiow ofthe lubricant. The movements of the rod and springs F are covered by the cover K, which is soldered to the flanges B on either side, and extends from the point A' to the lower end of the receiverwall. The slots K' help to retain the cams H in their places, and from moving sidewise if the rod G- becomes loose by accident or otherwise. The points `H prevent the turning of the cams too far around by striking the surface of the cover K. The openings?` in the clamps L are intended to aid the lubricant to more readily saturate the wick. rlhe projection or indenture k on the lower edge of the back wall ofthe receiver, Fig. 12, prevents the clamps from leaving the receiver when the slide D is feeding out the wick, said indenture entering the hole L'l when the clamps are introduced within the walls of the receiver.

To more readily take the clamps L from the receiver, to insert anew wick and cleanse the parts to introduce different lubricating compounds, I form a iiange, L, on the clamp L', Fig. 14, the pressing in ot' which with the thumb relieves the clamps from the in denture 7.', and so permits the withdrawal. The opening l in the cover K is intended to give room for the thumb while withdrawing the Clamps.

ill denotes the wiok-comluctor, composed of lamp-wick doubled up as many times as iS necessary to entirely fill up the space between the clamps L and L', so when the clamps are inserted into the receiver the outside surface of the clamps will fit snugly the lower ends of the walls of said receiver and prevent any flow of the lubricant outside of the clamps. At the upper. end oi' the wick I Se curely fasten a protection-loop, O, so constructed as to have on each end a. curved point, O', that stands away from the wick, whose object is to prevent the wick from eeming entirely out of the clamps when nearly used up by striking against the indenture Li" on the clamp L, Figs. 15 and 17, which is turned inward from the lower edge of said clamp, and of the same description as the indenture 7.'.

N represents the handle to hold my device with, formed of wood or other substance, and inserted in the cap N', which is of the same material as the lubricator, and soldered on the back wall -of the receiver.

lVhile I can still use my lubricator for the purposes spoken of in my last patent, my design in the present invention is to provide a lubricator in which I can employ oil, turpentine, or any-other class of liquids, and so devote my device to many uses-such as the oiling of a circular saw while in motionthe oiling and staining of woods and furniture, the oiling of machinery and line castings to prevent rust, and many other articles of use where only a little lubricant is desired.

Vhat I claim, and desire to secure by Letters Patent of the United States, is-

1. In a lubricator, the combination of the reservoir A, the receiver I, the blanks B2, provided with ilanges B, and shoulders c and d, the feed-slide D, and teeth D', the thumbpiece D2, the springs E with a wick, M, the whole operated as described and set forth.

2. In a lubricator, the combination of the reservoir A, the receiver B, the blanks B2, provided with flanges B", the springs F, the rod G, the thumb-piece f, the cams H, the points H', the clamps I, provided with screw J the cover K, and openings K', with clamps L and L', provided with lip L2, and wick M, all for the purpose described and set forth.
